Osteoporosis in Male Ankylosing Spondylitis Patients

Agreement between the two methods done for evaluation of disease activity was carried out (BASDAI & ESR) but was not statistically significant. After DEXA was done six patients had normal BMD & 8 had low BMD both spinally & femorally. Two patients had low femoral BMD with normal spinal BMD & 4 patients had normal femoral BMD with low spinal BMD. The frequency of patients with normal or low BMD (femoral or spinal) based on T-score is shown in Table (3). Their distribution among the late and the early group is illustrated as well. Spinal osteoporosis was more common than femoral osteoporosis among the early group. As for the late group, femoral osteoporosis was more common than spinal osteoporosis. That is the more time elapses the more spinal BMD increases despite the presence of osteoporosis which makes femoral BMD more reliable for comparisons
